Hydro-Québec Espionage Trial Exposes Internal Oversight Failures

A significant espionage trial involving former Hydro-Québec researcher Yuesheng Wang has highlighted internal oversight failures within the organization. Wang, who has been charged with economic espionage benefiting China, was not questioned by senior managers regarding concerns raised by publications in 2022 that triggered an internal investigation.

During the trial, Patrick Cyr, a manager overseeing Wang, stated that there was no obligation to confront Wang about the issue. The case has drawn attention as it marks the first instance of a charge under Canada’s Security of Information Act. Wang has pleaded not guilty and faces multiple charges, including fraudulent use of a computer and breach of trust, stemming from incidents occurring between 2022 and 2024.

Cyr explained that initial findings indicated a violation of Hydro-Québec’s internal rules when an academic paper was published in March 2022, with the company’s knowledge. “There were people internally who were doing the scientific work to validate: What were the publications?” Cyr testified. The crux of the prosecution’s argument is that Wang published work without obtaining the necessary approvals from Hydro-Québec’s intellectual property committee.

This committee is responsible for reviewing and approving any proposed articles, conferences, or patents. The federal Crown alleges that Wang was involved in the Thousand Talents program, which aims to attract foreign-trained scientists back to China to advance its technology development. Wang is accused of committing to assist Chinese entities in commercializing battery technologies related to confidential research at Hydro-Québec.

Cyr acknowledged that he had contacted corporate security for an internal analysis of Wang’s scientific activities after discovering the first publication. He emphasized that confidentiality is crucial at Hydro-Québec’s research institute, the Center of Excellence in Transportation Electrification and Energy Storage (CETEES), located in Varennes, Quebec. Much of the research conducted there pertains to advanced battery technologies, and access to sensitive information is tightly controlled.

Wang, who joined Hydro-Québec in 2016, has been noted for not disclosing any interest in changing jobs. Employees are permitted to hold outside employment, but must declare it if it relates to the battery industry due to conflict of interest concerns. Cyr testified that Hydro-Québec has implemented stricter protocols since the departure of Karim Zaghib, the institute’s founder, including blocking personal electronic messaging services on company computers.

The trial has revealed that communications among staff were primarily in English, despite the organization’s predominantly French-speaking environment. Wang’s limited proficiency in French has raised concerns about his ability to fully engage with the company’s policies, which include annual mandatory code of ethics reviews.

The presiding judge, Jean-Philippe Marcoux, indicated that if Wang testifies, it may occur in Mandarin to ensure clarity, given potential language barriers. The prosecution has also suggested the possibility of calling additional witnesses not currently on its list.

The trial is set for a brief recess and will resume on October 27, 2025, at the Longueuil courthouse, located south of Montreal. This unfolding case continues to captivate public interest, raising questions about corporate governance and the safeguarding of sensitive information in the face of global espionage threats.
